To all whom 'it may concern:

Be it known that I, EGBERT MOXHAM, a citizen of the TLlnited states, residing at Wilmington, county of Newcastle, and State of Delaware, have invented a new and useful Improvement in Apparatus for Brewery Pitcliing-Macliines, `of which the. following is a full, clear, and exact description, reference. being had to the accompanying drawings, which form a part of this specification.

My invention relates to a new and useful improvement lin brewery pitching machines.

The object of my invention is to provide an automatic safety apparatus on the spray pipes of such machines, which will prevent the egress of the pitch from the spray pipes until the package to be pitched is in proper position to receive the pitch. In machines of this class, it is usual to use an o ien spray pipe covered on the end and only with a spraying nozzle. lf under these conditions, and before the package is placed in position, the pump or other source of power used to force the pitch up through the spray pipe should be accidentally started, the pitch is' forced out of the pipe in large quantities, severely burning the attendant.

The object of my invention is to provide an automatic safety apparatus, which will prevent the egress of pitch under all conditions, unless the package is in position, and when such package is in position, will automatieally al ow egress from the delivery noz zle, and the pitch to pass into the interior of the package. l

l will Afirst describe the embodiment ofiny invention as illustrated in the accompanying drawings, and then specifically point out the iivcntion in the claims.

ln the drawings: Figure 1 is a partial section illustrating the interior and exterior construction of one of the well known con structions of aii pressure brewery pitching machines 'fitted with my improved safety device. The left hand spray pipe is shown with thc safety device closed, while the right hand pipe is shown covered with a package andthe safety device open for the egress of pitch. Fig. 2 is an enlargei'l section of my iin roved safety device.

`n li'ig, 1, 1 is thepitcli kettle, consisting of three compartments 2, 2 and 3. The lower compartments 2, 2 are. separated from cach other by a central vertical wall and from compartment 3 by a horizontal wall cast integral with the kettle, in `which are vopen -connection when two openings suitably arranged for closure by the two removable heads 5, 5, in which f are carried the automatic valves 4,' 4, these valves` being covered by perforated, screens 6, 6. These valves 4, 4when pressure is applied to chambers 2, 2, close connectionbetween said chambers and chamber 3 and `s aid pressure isl re leased. The kettle is provided with a cast iron cover 7, in which ,is the removable door 8, and integral with which are the package supports 9, 9. There is an openin 18 in the cover 7 at the lower end of the wa l forming the package support. as sing' .through the cover 7 and connecting with the lower chambers 2, 2, are the air ressure pipe-slt), 10, suitably controlled y .the two-wa valves 11, 11, links and hand levers 1212. ,From close to the bottom the-delivery or spray pipes 13, 13 project u Ward, ending usually in spra nozzles. ie package is placed with the ung over these nozzles and rests on package supl'iiorts 9, 9, while being. pitched. On the enc spray or delivery pipes 13, 13, my. im roved safetya paiatus (shown enlarged in *i 2) is place In addition to the foregoing t ere is shown in Fig. 1 the usual safety valves 15,

thermometer 16, vapor escape pipes .27, etc., 85

ordinarily fitted tothis kind cf machine.

The operationof the machine is as follows: The, removable door 8 and the heads 5, 5, are removed from their position andchambeIs 2, 2 filled with from an externa source (not shown) an; the heads 5, 5, replaced and tightly clamped in their position, the up er compartment 3 of the kettle being art yilled with pitch at the same time. gravity, and when the melted down, chambers filled, and strainers 6, 6, well covered ,With pitch. A ackage is then placed over either spray nozz e, and the air valve 11 means of lever 12. Through pipe 28, from" suitable source (not shown) air und sure enters the lower chamber 2, automatically closing valve 4 and forcing the pitch up pitch is completely 2, 2, will be entirely through the spray pipe and into the package'f 105 rlhe surplus pitch drains cnt thebung hole of package and back into the u per chamber 3 of the kettle through suitable oienings 18. When the air pressure is shut off, the pressure in chamber 2 is relieved through the sec- 10 oiidary opening of airvalve 1] valvefl o )ens by gravity, and chamber 2 is again filled of chambers 2, 2,J

of. these so itch. Heat is ythen ap ilied alves 4, 4, remain open by openediby ico er presmyself Y pitching machine,

With pitch by gravity from supply in chamber 3.

Reierrin to Fig. 2 in which iny safety apparatus is s ioivn enlarged: The upper end of the spray or delivery pipe i3 is closed by the plug 21. Surrounding the Aspray pipe 13 is 'the casing 2? which extends beyondthe pipe i3 and has on its upper end the spray nozzle 28. In the spray or delivery pipe is the slot 24 into Which'theset screw 25,"Which passes Between the' 'seat in projection 3Q on the casing, and the through casing 23, enters.

Washer 19 on the pipe 13, is the spring 20. In the side oi the pipe 13 near the top, is the port 22. In the projection 30 of the casing is the relief passage 26, and-the by-pass 27. Carried by the casing 23 are the package enfgaging fingers 29. .liith the parts in the position shown. in Fig. 2, any pitch forced into the delivery pipe 13 by the premature action of 'the urnp or pressure device, will pass out through the port 22 into the relief passage 26, and through the o enings 1S to the compartinent 3. When t e` nozzle is inserted in the bung, and the ache-ge rests upon the fingers, its Weight Wil force the casing downward against the action oi? the spring until Weight oi package rests on package support 9. This movement will cause passage 26 to pass beyond port 22, and oy-pass 27 to register with said port. rlflnis when the package is in position, the itch is enabled to ass freely to the interior o the package, and t e apparatus is such that this can only talie place when the Apackage is imposition to receive the pitch.

At the right hand. of Fig. l, the safety apparatus is snown in position to deliver pitch to the interior of the package, While at the left hand, the apparatus is shown in position it assuineswhen the package is not in position and the spring 2U holds the casing in such position that the port 22 communicatesv with the relief passage 26.

While I have described and shown my irnproved safety device as attached to one spe cial form of air pressure itching machine for the sake of illustration, do not wish to limit to this special forni of air pressure or this particular vstyle of ina-chine, as the safety device Will Work with equally good results on any forni or style of pitching machine.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
